Here is the pics before and sat i will update after shots. Opinions?

This story it's almost like an urban legend.When the powder coating is cured correctly it should not affect the original temper of the alloy wheels.Powdered coating typically involves temperatures below 500 degrees. Too low to effect any wheel metallurgy. Either way i would feel safer riding on powder coated stock wheels than any aftermarket wheels.
Do it and let us know how it goes.
Silver on black wheels looks awesome!

Caps were pain in the ass to strip the chrome(the right way done) and coat it black

I'm not sure of what alloy the wheels are made, but there have been many instances of aluminum diving cylinders ( another high strength, forged aluminum alloy component) catastrophically failing after exposure to elevated temperatures. One manufacturer, Luxfer, has issued a warning to test any cylinder that had been exposed to temperatures between 265 F (130 C) and 350 F (175 C) due to metallurgical weakening.
Full annealing (complete removal of heat treated strength) of most alloys occurs completely after exposure to 645 F (340 C).
Just be aware that the powder coating process does actually heat treat aluminum alloy components, and it most certainly will reduce the components strength.
Perhaps this is why wheel manufacturers prefer to conventionally paint (or plate) alloy rims??
Wow! Taking things out of context, or what! A pressurised aluminium cylinder has no bearing on this. there are so many things that have to be taken into account. Material is the only thing in common!. Thickness, type, etc, etc...!

Not out of context at all, just reviewing some basic engineering principles, for people that may have misconceptions
Merely saying that the temperatures experienced in powder coating may have an serious effect on the mechanical strength of aluminum alloys, and gave some factual numbers to support.
Diving cylinder under pressure is in tensile stress, what do you think a large mass, rotating at speed, and subjected to large axial rim forces experiences?
Put it another way, how many racing teams, or perhaps manufacturers of aircraft landing wheels, use powder coat on their aluminum alloy wheels?

Very nice.
I really like the black wheels on the Cool Silver Touareg.....of course, i am biased though.

I'd be curious to see how these rims have held up since they were done almost a year ago. Any updates? I have 19's and the clear coat on them is starting to bubble in areas... debating getting them powder coated. Thanks
